QB$3.$ Given the data in Table QB$3$ for adsorption of ethanol on a mesoporous

carbon at $28C,$ at which temperature the saturated vapour pressure for

ethanol is $70\mathrm{.}9\frac{m}{b}ar,$ and the molar heat of condensation for ethanol is

$-38\mathrm{.}56kJmo{l}^{-1},$ determine:

i$)$ the value of the $C$ constant for the process

$[4$ marks$]$

ii$)$ the monolayer coverage

$[4$ marks$]$

iii$)$ the heat of adsorption

$[4$ marks$]$
